Title: Method for adding rare earth element to iron alloy
Inventor: KARASHIMA KAZUO
IPC: C22C33/04
Filed: 1987-04-24
Abstract: PURPOSE:To add rare earth elements to an iron alloy with a good yield and to produce a cleaned steel contg. less nonmetallic inclusions caused by the addition of rare earth elements by preliminarily applying the molten steel to vacuum deoxidation, subjecting it to a deoxidizing treatment, adding rare earth elements to the molten steel in the form of a base alloy with iron and thereafter casting the same. CONSTITUTION:The molten steel to be treated is applied to the vacuum deoxidation by utilizing a vacuum degassing apparatus, etc., to decrease the O2 content (O2) in the molten steel to <=20ppm at the time of adding rare earth elements such as La, Ce, Pr, Nd, Y, etc., to the molten metal of a high-speed steel, alloy tool steel, etc., so as to improve the characteristics thereof. Al is then added to said molten steel in a vacuum or in an inert gas atm. such as Ar, etc., to subject the same to the deoxi dizing treatment. The Al addition ratio is controlled to obtain 0.02-0.5wt.% residual Al in the molten steel and (O2) in the molten steel is regulated to <=10ppm. Rare earth elements are then added to the molten steel in the form of the base alloy consisting of 50-90% Fe and the balance rare earth elements in <=0.05Torr vacuum, ordinary pressure having 0.001% O2 content or vacuum inert gas atm. and the molten steel is thereafter cast in a vacuum or inert gas atm. contg. oxygen partial pressure corresponds to 1X1/10<7>atm.

Title: Tape reel and its production
Inventor: GENDOUSHI NAOKI
IPC: B29C39/26
Filed: 1984-05-18
Abstract: PURPOSE:To obtain a light-weight tape reel with low cost by providing equidistantly plural pieced holes which are tapered toward the outer surface from the inner surface of flange of a reel main body, and reducing the heat shrinkage and improving the molding accuracy. CONSTITUTION:The outer surface of a hub 2 of a reel main body 1, an inner surface 6a of a flange 6, a pierced hole 16 and a molding projection 18 are formed with a female metallic mold 8. While a hub hole 3, a hub pawl 4 and a flange outer surface 6b are formed with a male metallic mold 9. Thus the main body 1 is formed. The flange 6 has plural pierced holes 16 formed equidistantly, therefore the thickness of the flange 6 is reduced in its diameter direction T. In such a way, the effect of the heat shrinkage to the hub outer circumferential surface 12 is reduced, and the surface 12 can have a real circular shape. In addition, no flash is produced inside the reel sine the mold matching is carried out at the outside 6a of the flange 6. Then the weight of the reel is reduced to eliminate the function of the force of inertia and also to reduce the cost.

Title: Rotational frequency limiter for horizontal internal-combustion engine
Inventor: ARIMA YOSHIMI
IPC: F02D1/02
Filed: 1985-05-13
Abstract: PURPOSE:To prevent an intentional maximum engine speed from going up, by setting the position of an engaging point of a spring, whose one end engages with a governor lever, to a regulator lever, to a spot where energizing force of the spring becomes smaller, even if the regulator lever is turned round yet more to the speed-up side. CONSTITUTION:A maximum speed limiting bolt 23, checking the overrotation of a regulator handle 22 in a speed-up direction is attached to an outer surface of an engine wall 2. And, a regulator spring 20 is engaged with both tips of a regulator lever 18 and a governor lever 9 rotatably coupled in one via the regulator handle and a regulator lever shaft 16. According to this method, the position of an engaging point of the spring 20 to both these levers 18 and 9 is set so as to become a symmetrical position centering on a shaft center of the lever shaft 16 when the handle 22 is turned round to a maximum speed setting position, whereby such a possibility that one intentionally, cuts a seal of the bolt 23 and tries to increase the maximum engine speed is preventable.

Title: Heat accumulating material
Inventor: NOMURA KAZUO
IPC: F28F23/02
Filed: 1981-06-29
Abstract: PURPOSE:To prevent supercooling of a heat accumulating material, by adding brium acetate to a heat accumulating material of CaCl2.6H2O as a nucleator for preventing supercooling of the heat accumulating material. CONSTITUTION:Barium acetate is added to CaCl2.6H2O as a nucleator for preventing supercooling. Although the nucleator is added at a rate higher than the solubility of the same, it is practically preferable that the amount of the nucleator to be added to CaCl2.6H2O is less than 10wt% of CaCl.6H2O. A thickening agent can be added further to CaCl2.6H2O for the purpose of improving diffusion of the nucleator. As the thickening agent, a high-molecular substance such as carboxymethylcellulose that is dissolved in a heat accumulating material is used. Resultantly, it is enabled to obtain a heat accumulating material capable of preventing supercooling and having a stable performance, absorbing and releasing heat at a fixed temperature.

Title: Load torque detector for induction motor
Inventor: KAWADA SHIGEKI
IPC: H02P23/00
Filed: 1979-08-10
Abstract: PURPOSE:To detect the load torque stable over wide speed range by applying a signal obtained by proportionally integrating a deviation signal between a speed instruction signal and an actual speed signal to an ammeter. CONSTITUTION:When the load torque is increased in the induction motor, there occurs a difference between the actual speed signal from a tachometer generator 3 and the speed instruction signal, and a proportional integrating amplifier 5 integrates the signal and produces a signal becoming higher as the time goes. The output signal is added to a frequency signal responsive to the actual speed signal by an adder circuit 10 to obtain a control signal compensated for the slip frequency. When the output of the amplifier 5 is displayed on the ammeter 6, the magnitude of the load torque can be gained.
